Great performance, basically two 100 watt solar panels wired in parallel putting out 160 to 170 watts into a solar generator with a good MPPT controller. The connector is an Anderson power pole with the plugs stacked vertically instead of the common side by side plugs. I needed an Anderson to 8mm adapter cable to connect to my solar generator. Also the Goal Zero is quite heavy, I don't recommend trying to carry it very far but it has very high quality frame and glass. I'm probably going to buy a second one!

I buy GoalZero for reliability and quality of builds, and this product satisfies both. Solid case, and well built unit. My boulder 200 has been mounted to the back of my truck, feeding my Yeti PowerStation directly. When couple with the direct connection to my alternator, I can rapidly re-charge a depleted PowerStation with ease. It's been installed over the bed of the truck, and the materials are holding up to the heat and weather with no problems. Overall very happy with this unit.

Works well and I like the kickstand and portability, but could be lighter for the price.

Awesome well built very nice. Would recommend and buy again

Very easy set up. Plug it in and charge your generator or batteries no problems.
